摘要(Abstract)：

针对空间同位模式能求出空间实体的关联集聚现象,但不能求出组成同位模式的实体元素的贡献大小的问题,该文通过引入粒计算和概念格中的概念粒概念,把每一种同位模式的元素都看作一个概念粒。利用概念粒之间距离和概念熵的度量,在概念粒中减少实体存在的原子公式,从而计算每个空间实体对于同位模式形成的重要度。通过对组成南宁市服务业空间同位模式重要因子的实例研究,该方法能有效地求出城市服务业的空间同位模式,并能找出每一种空间同位模式的重要因子。该方法不仅能提供计算形成同位模式重要因子的数学基础,更是一种全新的思考空间关联关系的思维方式。

关键词(KeyWords)： 概念粒;同位模式;重要度;概念格;粒计算
